BACKGROUND OF THE INVENTION

The present invention relates generally to a method of making an animalfeed and in particular an improved milk replacer having a soluble fiberand a sugar alcohol.

Livestock are generally weaned prior to their ability to consume wholefoods. In the case of dairy cattle, calves may be fed whole milk or amilk replacer until the calves are weaned and ready to consume solidfood. Feeding calves milk replacer is generally preferred since the milkreplacer not only mimics the milk in terms of protein, fat andcarbohydrate content, but also may be fortified with vitamins,medication and other nutritional supplements which benefit the youngcalves. Furthermore, milk replacer is a powder that has been spray driedat high temperatures eliminating disease organisms that may have existedin the ingredients that comprise the milk replacer. The powder form ofthe milk replacer also provides for easy storage.

Young livestock such as calves, piglets, horses, sheep, goats and otherruminants are very susceptible to bacteria that cause scours (diarrhea).Scours can lead to dehydration of the young animal and many studies havebeen conducted that show when young animals have experienced scours,their growth and development is less than animals that have notexperienced scours. Less growth and development, of course, results inless profitability for the farmer.

It has been suggested that adding psyllium to milk replacer may beeffective in reducing scours in calves. Martin J. Fettman, PotentialBenefits of Psyllium Mycelioid Supplementation of Replacement Formulasfor Neonatal Calf Scours, North America, Ed., February 1992, at 247(Fettman Article). The Fettman Article based its opinion upon theproperties of psyllium as well as the effectiveness of psyllium inreducing intestinal disorders in other animals and humans.

The use of psyllium (plantago seed supplement) in animal feed is alsodisclosed in Van Magius, PCT Patent Application No. WO82/02650 (VanMagius Patent). The Van Magius Patent application describes usingplantago seed supplement to reduce animal stress conditions, prevent ortreat scours, and promote growth.

Further use of a stable suspension of psyllium and the calf milkreplacer has been described in the Miller et al. U.S. Pat. Nos.5,571,542 and 6,406,729. In addition, the use of sorbitol as a feedcomponent for cows is described in the Luhman U.S. Pat. No. 6,440,447.

Weaning of young animals occurs when the liquid feed is withdrawn fromthe diet. Thus, as used herein, “pre-weaning period” refers to theperiod when nutrients are predominantly or entirely supplied in liquidform such as to a calf as part of a liquid feed, and “post-weaningperiod” refers to the period when nutrients are no longer predominantlyor entirely provided to the calf in the form of liquid feed.

Typical liquid feeds for young animals include fluid milk or fluid milkreplacers. In the case of dairy cows fluid milk replacers are frequentlysubstituted in place of fluid milk because fluid milk that is producedby mature, lactating dairy cows is generally more valuable when sold toconsumers or when used to manufacture food products that are sold toconsumers. Thus, fluid milk replacers that are produced to simulatefluid milk are generally substituted in place of fluid milk for feedingyoung calves. Fluid milk replacers may be based upon dairy componentsand non-dairy components that are combined to provide nutrient andpalatability characteristics approximating the nutrient and palatabilitycharacteristics of fluid milk. Milk replacers are typically marketed inpowdered form to avoid the higher transportation and storage costs ofdistributing fluid milk replacer. Powdered milk replacers are mixed withwater prior to use to form fluid milk replacers that are provided to theyoung calves. The formulation and feeding of fluid milk replacers iswell-known in the art.

Ruminants, such as cattle, are commonly bred and raised to produce foodproducts, such as milk and beef, for human consumption. Maturation ofcattle, as evidenced by weight gain, is an important factor that helpsdetermine when a cow is ready to produce milk or is ready for market.Dairy farmers and cattle ranchers are greatly interested in techniquesfor economically achieving enhanced rates of ruminant weight gain sincesuch techniques beneficially reduce milk and beef production costs.

Also, dairy farmers and cattle ranchers recognize that the care andfeeding of cattle both prior to weaning and after weaning play animportant role in determining the amount and quality of productsproduced by the cattle. As an example, the age of dairy cows atfreshening and the onset of lactation may be reduced by modifying thenutrient mix and nutrient composition in feed the dairy cows consume andby inducing the cows to gain weight more quickly during the pre-weaningand post-weaning periods prior to freshening. Also, in cattle ranchingoperations, increasing the rate of weight gain by young cattlebeneficially reduces the time required for producing cattle with a sizethat is suitable for market.

In both dairy operations and ranching operations, it is also generallydesirable to increase the feed efficiency of young ruminants. Thegreater the feed efficiency the less feed required by the ruminant toobtain a unit amount of weight gain.

A major overall desire of dairy farmers and ranchers alike is to reducethe overall cost to produce a product, such as milk or beef, with anacceptable level of quality. Depending upon numerous cost variables,such as the cost of feed, labor costs on the farm or ranch, andequipment and building costs on the farm or ranch, this desired costreduction may be achieved by increasing the rate of weight gain by youngruminants and/or increasing the feed efficiency of young ruminants.Thus, dairy farmers and ranchers, depending upon their particular costvariables, may employ either enhanced rates of weight gain or increasedfeed efficiency or a combination of enhanced rates of weight gain andincreased feed efficiency to reduce the cost of bringing milk and beefto the consumer market.

To complement liquid feeds that are fed to ruminants, such as cattle,prior to weaning, a number of additives and supplements have beendeveloped for feeding calves along with the liquid feed during thepre-weaning period. These additives and supplements have been developedfor a number of different purposes. For example, some additives andsupplements have been developed to generally enhance the health of theyoung calves or help prevent or control development of specificconditions or ailments, such as scours. Additionally, some additives orsupplements have been developed in an attempt to enhance appetite,enhance maturation rate, and/or enhance weight gain.

In this regard, various veterinary pharmaceutical compositions have beendeveloped to help prevent or inhibit development of certain ailments inruminants. Also, numerous vitamin compositions have been developed tohelp enhance the general health of ruminants and/or to help prevent orinhibit development of ailments or conditions in ruminants. Finally, theuse of psyllium has been prescribed for reducing scours in calves. Also,psyllium incorporation in the diet of ruminants has been described forincreasing the rate of weight gain per unit weight of protein that isconsumed by ruminants.

Though the various ruminant feed supplements and additives that havebeen proposed and/or practiced over the years have enhanced the overallknowledge base with respect to ruminant feeding, these feed supplementsand additives, as well as feeding techniques that employ these feedsupplements and additives, have not yet been fully identified,addressed, or optimized options for increasing the rate of weight gainexhibited by ruminants or for increasing the feed efficiency ofruminants. Thus, dairy farmers and ranchers alike are still in need ofnew approaches to feeding ruminants that enhance weight gain rates inruminants and/or increase the feed efficiency of ruminants.

SUMMARY OF THE INVENTION

The present invention includes an animal feed such as a milk replacerhaving a soluble fiber and a sugar alcohol and a method of making thesame. The milk replacer enhances weight gain, starter intake and reducesweaning time. The present invention also includes a method of feeding ananimal a mixture of a soluble fiber and a sugar alcohol. The presentinvention further includes a method of making an animal feed thatincludes a soluble fiber and a sugar alcohol. The present invention alsoincludes a method of weaning a ruminant such as a calf by feeding theruminant a soluble fiber and a sugar alcohol. The present invention alsoincludes a calf milk replacer containing an effective amount of psylliumand a sugar alcohol for reducing weaning time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

It has been found that an animal feed such as a calf milk replacercontaining both a soluble fiber and a sugar alcohol enhances weightgain, starter intake, and reduces weaning time. In addition scourseverity is also reduced. Calves fed an enhanced amount of milk replacerare especially benefited. Although the present invention has been foundvery suitable in weaning calves, the present invention is suitable forall livestock. By livestock is meant agricultural animals such as swine,horses and ruminants such as but not limited to cows, sheep and goats.

Psyllium is the preferred soluble fiber used in the present invention.By soluble fiber is meant that part of plant foods that cannot bedigested or absorbed and that readily disperses in an aqueous solution.Soluble fibers may include gums, hydrocolloides, most pectins, mucilagesand some hemicelluloses. Psyllium is a hemicellulose. Preferably thepsyllium should be in the form of a powder with a fine particle size.The fine particle size helps to disperse and maintain the particles ofpsyllium in solution and helps to enhance the rate of water absorptionand the amount of water absorbed by the psyllium. The psyllium ispreferably fed at approximately 16 grams per day and preferably at leastapproximately 6 grams per day and up to approximately 19 grams per day.The use of psyllium above 19 grams per day may still have the effect ofthe present invention but usage above 19 grams per day is lesseffective.

In the specific embodiment described herein, the psyllium is fed to acalf as a component of a milk replacer. The milk replacer is fed at anenhanced rate to the calf. Preferably, the enhanced feeding rate for themilk replacer is at least about 1.5 pounds of the milk replacer per daybased on the dry weight of the milk replacer during the pre-weaningperiod.

Sugar alcohols useful in the present invention include adonitol;allitol; altritol (D-altritol, L-altritol, and D,L altritol); arabinitol(D-arabinitol, L-arabinitol, and D,L arabinitol); dulcitol (a.k.agalactitol); erythritol; galaxitol; glucitol (D-glucitol, L-glucitol,and D,L glucitol); glycerol; iditol (D-iditol and L-iditol); inositol;isomalt; lactitol; maltitol; mannitol (D-mannitol, L-mannitol, and D,Lmannitol); perseitol; ribitol; rhamnitol; sorbitol; threitol(D-threitol, L-threitol, and D,L threitol); and xylitol. These sugaralcohols may be provided in any combination. All such sugar alcohols incombination with psyllium have the effect of the present invention.Preferably sorbitol is used due to its relative low cost in relation tothe other sugar alcohols. Sorbitol was preferably fed at a rate ofapproximately 5 to 6 grams per day along with the amounts of psylliumdiscussed previously. Sorbitol is consumed preferably at leastapproximately 3 grams per day to have an effect and up to approximately8 grams per day. Amounts of sorbitol ten grams and over per day werefound not to have the same effect as the present invention. Therefore,it is preferred for the animals to consume approximately less than 10 gper day.

The sugar alcohol(s) is fed to the calf as a component of the milkreplacer. The milk replacer includes the animal feed of the presentinvention such as the milk replacer is made by adding the sugar alcoholinto the dry milk replacer (containing psyllium). The milk replacer (nowcontaining the sugar alcohol and psyllium) is then hydrated by thefarmer or rancher for feeding to the calf.

The method of the present invention is described in the followingexample. This example is provided as an illustration of the inventionand is not intended to limit the invention in any way.

Example

A total of 56 calves were provided with the milk replacer of the presentinvention in three separate trials. The sugar alcohol used in thesetrials was sorbitol. The calf milk replacer (CMR) used was Cow's Match®from Land O'Lakes, Inc of Arden Hills, Minn. Cow's Match® containsapproximately 1.38% psyllium. The results from the three trials werecombined and are set forth below in Tables 1 through 4. The proceduresfollowed in all three trials were similar.

The calves used in the trials were approximately 3 to 10 days old at thetrial's initiation. Each calf was weighed initially upon arrival andweekly thereafter. Other performance parameters were determined on adaily basis.

As Table 1 set forth below indicates, a significant gain in weightoccurred in the calves in periods 1 and 2. These periods correspond tothe first two weeks of the trials. In addition to the first two periods,the total weight gain for the seven periods for calves fed Cow's Match®with sorbitol showed approximately 7.9% greater increase over the calvesnot fed the sorbitol.

There was also a significantly greater starter intake by the calves fedCow's Match® with sorbitol in periods 2 through 5. Total starter intakeby calves fed Cow's Match® with sorbitol was 17.7% greater than calvesnot fed sorbitol. This was also statistically significant.

The calves fed Cow's Match® with sorbitol showed a significant decreasein period 1 in severity of scours (scour score), and the number of scourdays experienced. Data was grouped and considered for the first twoweeks (first two periods) since scouring is most prevalent in the firsttwo weeks. Scour severity was significantly reduced in the first twoweeks for the calves consuming psyllium with sorbitol as compared to thecalves not being fed sorbitol.

A further trial was ran to determine what effect sorbitol without adietary fiber would have on calves fed an intensified diet of calf milkreplacer. Forty-six three to ten day old Holstein bull calves weighingapproximately 90 to 100 pounds were fed an intensified diet of calf milkreplacer. Twenty-four calves were fed a calf milk replacer withoutpsyllium and without sorbitol and twenty-two calves were fed calf milkreplacer without psyllium but with sorbitol. The latter 24 calves werefed 6 grams each per day of sorbitol.

As Table 5 set forth below shows, there was no statistically significantdifference in total weight gain, calf milk replacer consumption, starterfeed intake and average feed:gain (feed efficiency) between those calvesfed no sorbitol and those calves fed 6 g per day of sorbitol.

Data for parameters presented in the Tables above was analyzed using thegeneral linear model (GLM) statistical procedure of SAS™. Statisticalanalysis software for a randomized complete block design that includedboth the particular feed regimen and the week of the test period in themodel statement. The SAS™ statistical analysis software is availablefrom SAS Institute, Inc. of Cary, N.C. Additionally, all data wasanalyzed to determine the mean of the data for each variable underconsideration during the collection period for the particular data.

Additionally, the PDiff function of the GLM statistical procedure wasused to characterize the mean values of the data by providing forcomparisons between mean data values for the calves of differenttreatments for particular test parameters or variables.

P used in the Tables above is a probability value. For purposes ofcomparing data in this document, P values of 0.10, or lower, areconsidered to be statistically significant. Thus, where a P value of0.10 or less is returned for a particular variable, it is assumed thatthe differing results are fully explained by the test regimen, i.e. thepresence or lack of sorbitol.

Also, the Tables include a coefficient of variation (CV) for data in aparticular row. The coefficient of variation is the standard deviationof a particular variable divided by the mean of the variable and thenmultiplied by 100.

Although the present invention has been described with reference topreferred embodiments, workers skilled in the art will recognize thatchanges may be made in form and detail without departing from the spiritand scope of the invention.

What is claimed is:
 1. A method of feeding a young livestock animal, themethod comprising: feeding the young animal a soluble plant fiber andsorbitol dispersed in an aqueous solution and a starter feed, wherein inresponse to ingesting the aqueous solution and the starter feed, theanimal increases a rate of weight gain.
 2. The method of claim 1 whereinthe animal consumes at least about 3 grams and up to 6 grams of thesorbitol per day.
 3. The method of claim 1 wherein the animal consumesat least approximately 6 grams of the soluble plant fiber per day. 4.The method of claim 1 wherein the animal consumes up to approximately 16grams of the soluble plant fiber per day.
 5. The method of claim 1wherein the young animal is a ruminant, a piglet, or a foal.
 6. Themethod of claim 5 wherein the ruminant is a calf.
 7. The method of claim1 wherein the aqueous solution comprises a milk replacer.
 8. A method offeeding a young livestock animal, comprising: feeding the animal a milkreplacer comprising a soluble plant fiber from at least approximately0.53 percent of the milk replacer on a dry weight basis and sorbitol,wherein the animal consumes at least about 3 grams and up to 6 grams ofsorbitol per day.
 9. The method of claim 8 wherein the sorbitol is fromapproximately 0.26 percent of the milk replacer on a dry weight basis.10. The method of claim 8 wherein the sorbitol is up to approximately1.76 percent of the milk replacer on a dry weight basis.
